⚖️Metal Weight Calculator

Select metal type, enter width × height × length in mm, and get the weight in kg instantly.

How to Use the Metal Weight Calculator

Enter the width, height, and length of a rectangular metal block in millimeters, then select the metal type. The calculator applies the formula: Weight (kg) = W × H × L (mm) × Density (g/cm³) ÷ 1,000,000. Useful in manufacturing, metalworking, and construction for estimating material weight before cutting or ordering. Ten common metals are built in, including carbon steel, stainless steel (304/316), aluminum, copper, brass, lead, titanium, nickel, and zinc.

Frequently Asked Questions

What formula is used?

Weight (kg) = Width × Height × Length (mm) × Density (g/cm³) ÷ 1,000,000. Volume in mm³ converts to cm³ by dividing by 1,000, then multiplied by density gives grams, divide by 1,000 for kg.

What is the difference between density and specific gravity?

For practical purposes they are the same. Specific gravity is relative to water (1 g/cm³), so a metal's specific gravity and its density in g/cm³ are numerically equal.

What metals are included?

Carbon steel (7.85), SUS304 (7.93), SUS316 (7.98), aluminum (2.70), copper (8.96), brass (8.50), lead (11.34), titanium (4.51), nickel (8.90), zinc (7.14).
